Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base plate crushing device for a gaming machine such as a pachinko machine, and more particularly to a device for reliably separating nails from other crushed pieces such as wood pieces and plastic pieces for selection. Pertain.

[0002]

2. Description of the Related Art Generally, a gaming machine such as a pachinko machine has a quick change of user's preference, and therefore a game machine side frequently replaces with a new type gaming machine. And this old game machine that has been replaced is rarely reused as it is as an old type, and even if the game machine is disassembled, nails etc. that are firmly driven in the thickness direction from the surface of the base plate are pulled out. Because it takes a huge amount of time to disassemble it further and it is difficult to dismantle it, etc., there is no choice but to stack and store it in a specific place or simply incinerate it, and I am troubled to dispose of the game machine. The current situation.

Therefore, for example, Japanese Laid-Open Patent Publication No. 7-300355.
As disclosed in Japanese Patent Publication, after disassembling the game machine and crushing the disassembled base plate with a biaxial crusher, etc., it is sorted into wood pieces, metal pieces such as nails, plastic pieces, etc. A technology has been developed in which wood pieces and plastic pieces are used as auxiliary fuel for cement production kilns in cement production equipment, and the generated incineration ash is mixed in the cement as fly ash for reuse. .

[0004]

By the way, when the wood pieces and the plastic pieces after the crushing of the base plate are reused as auxiliary fuel in the cement manufacturing apparatus, the metal pieces that impair the quality of the cement are reused in the wood pieces and the plastic pieces. It is necessary to ensure removal prior to incineration at the time of use.

However, in the example of the above-mentioned publication, since the base plate is crushed into a desired size by a biaxial crusher together with metals such as nails, nails etc. which are firmly driven into the base plate are also crushed. The nails are crushed without stopping the original shape, and some of the nails (for example, legs) are selected as crushed pieces such as wood pieces and plastic pieces while being embedded in the wood pieces and the plastic pieces. In this case, even if the wood pieces and the plastic pieces are crushed into smaller pieces in the subsequent step, the nails and the like in the wood pieces and the plastic pieces are also crushed into smaller pieces and cannot be removed more and more. Therefore, if the wood pieces and the plastic pieces with the nails and the like buried therein are reused as the auxiliary fuel of the cement manufacturing apparatus, the quality of the cement is significantly deteriorated.

On the other hand, when the nail driven into the base plate is made of brass, the weight unit price of brass (brass) is higher than that of steel, so the nail (brass nail) is selected after crushing the base plate. There is also a demand for collection.

The present invention has been made in view of the above points, and an object thereof is to cut and crush the base plate so that the nails and the like can be selected in a state in which the original shape is stopped, and the wood pieces in the post-process. In addition, the present invention intends to ensure the selection of plastic pieces from metal pieces such as nails, and to reuse nails, wood pieces and plastic pieces.

[0008]

In order to achieve the above-mentioned object, a solution means provided by the invention as set forth in claim 1 is to provide a nail driven in the thickness direction from the surface side of a base plate of a gaming machine from the base plate. As a base plate crushing device for a game machine that crushes the base plate so that the base plate can be separated and sorted, a guide supporting unit that guides and supports the base plate with the surface of the base plate facing downward, and the guide support. A feed roller that is rotatably provided above the means and moves by pressing the base plate against the guide supporting means from above by a rotating operation; and a feed roller that is rotatably provided downstream in the feed direction of the base plate over the entire width of the base plate. And a cylindrical rotary blade having a cutting and crushing blade on the entire circumference for cutting and crushing the downstream end of the base plate in the feeding direction by a rotating operation.

Thus, in the invention according to claim 1, the base plate separated from the gaming machine moves while being pressed against the guide supporting means by the feed roller, and the cutting crushing blade of the rotary blade causes the base plate in the feed direction downstream end. More cutting and crushing. Therefore, the base plate is in a direction orthogonal to the base plate,
In other words, cutting and crushing with a cutting crushing blade is performed from a direction parallel to the nail driving direction, and metal pieces such as nails are crushed with a biaxial crusher, like metal pieces such as nails are cut into wood. It is not embedded in crushed pieces such as pieces and plastic pieces, and nails and the like are separated from wood pieces and plastic pieces in a state where they are almost kept in their original shape,
A metal piece such as a nail and a wood piece, a plastic piece, or the like can be easily selected in a subsequent process.

The means for solving the problems according to the invention of claim 2 is as follows.
The rotation direction of the rotary blade of the invention according to claim 1 is specified, and the rotation direction is opposite to the driving direction of the nail on the base plate on the guide support means.

Thus, in the invention according to claim 2, the nail or the like is knocked down by the cutting and crushing blade from the pulling direction that is most likely to come off without damaging the head of the nail, and the wood piece and the plastic in a state closer to the original shape. Separated into pieces.

The means for solving the problems according to the invention of claim 3 is as follows.
A configuration in which the bed plate of the invention according to claim 1 or 2 is specified, and is guided and supported by the guide support means in a state where the back surface is substantially aligned with the normal line of the circle drawn by the rotation locus of the cutting and crushing blade of the rotary blade. It is what

Accordingly, in the invention according to claim 3, the back surface of the base plate is cut from a direction substantially orthogonal to the cutting and crushing blade, and the nail and the like are surely cut by the cutting and crushing blade from the pulling direction where it is most likely to come off. It is beaten off and separated into pieces of wood and plastic.

The means for solving the problems according to the invention of claim 4 is as follows.
In addition to the constituent features of the invention described in any one of claims 1 to 3, a jumping-up prevention means for preventing a jumping up of the base plate on the upstream side in the feeding direction is provided between the rotary blade and the feeding roller. It is configured to be provided.

As a result, in the invention according to the fourth aspect, the upstream end in the feeding direction of the base plate, which is shorter on the side of the rotary blade than the feeding roller, is on the guide supporting means although the pressing by the feeding roller is stopped. The upper end of the base plate in the feeding direction is pushed by the downstream end of the following base plate in the feeding direction and is reliably crushed by the cutting and crushing blade.

Further, the solution means taken by the invention of claim 5 is, in addition to the constituent features of the invention of any one of claims 1 to 4, below the rotary blade,
The entrainment preventing means for preventing the base plate crushed pieces cut and crushed by the rotary blade from being caught in the cutting crushing blade is arranged in the vicinity of the rotation locus of the cutting crushing blade.

Thus, in the invention according to claim 5, a long metal piece or the like which is sequentially separated from the surface of the base plate by the cutting and crushing blade is peeled off and moved to the cutting and crushing blade side with its tip hanging down. Even so, the long metal fittings are surely prevented from being caught in the cutting crushing blade and separated together with other crushed pieces (metal pieces, wood pieces and plastic pieces), and also caught in the cutting crush blade. This prevents damage to the rotary blade.

Next, an example of a work procedure by the sorting equipment 1 will be described with reference to FIGS. 7 and 8.

First, after receiving all the unnecessary pachinko machines in a lump, in the disassembling step A, the workers use the existing tools such as a screwdriver and a crowbar to remove the pachinko machines from the front and the front. Frame, base plate 2, rear case,
The controller and cover are disassembled into six disassembled parts. Then, these six disassembled parts are divided into a base plate 2 and remaining disassembled parts such as an outer frame, a front frame, a rear case, a control unit and a cover, and the base plate 2 is left in the base plate crushing step B. The disassembled parts (outer frame, front frame, rear case, control unit, and cover) are each handed over to another crushing step C.

Next, in the base plate crushing process B, the base plate 2 separated in the disassembling process A is pressed from above by the feed rollers 46 with the left and right side edges on the front surface 2a side against the upper surface of each support bar 34. While being sequentially fed to the rotary blade 62, the cutting and crushing blade 61 of the rotary blade 62 cuts and crushes the base plate 2 from the downstream end in the feeding direction. At this time, the jumping up of the upstream end of the base plate 2 that is shortened by being guided toward the rotary blade 62 with respect to the feed roller 46 is prevented by the first panel material 71, and the downstream end of the subsequent base plate 2 in the feed direction is prevented. It can be reliably crushed by the cutting and crushing blade 61 when pressed by. In addition, the long panel of steel strip 4 or the like, which is sequentially separated or peeled off from the base plate 2 by the cutting and crushing blade 61, is caught in the cutting and crushing blade 61 by the second panel material 72.
Is prevented by the second panel member 72 without getting caught in the cutting crushing blade 61 even if the long steel strip 4 or the like approaches the cutting crushing blade 61 side with its tip hanging down. It is possible to separate together with the wood piece, the plastic piece, and the steel part piece, and it is possible to prevent damage to the rotary blade 62 due to being caught in the cutting and crushing blade 61.

The base plate 2 cut and crushed by the base plate crushing device 6 includes brass nails 3, wood pieces (base plate portions), plastic pieces (plastic panels and various plastic products), and steel part pieces. (Steel band 4 and split pin 5). At this time, the brass nail 3 is biaxially crushed by rotating the blade 62 of the base plate crushing device 6 in the opposite direction opposite to the driving direction of the brass nail 3, thereby crushing the base plate together with metals such as brass nails. Like something that is crushed by a machine,
The brass nails 3 and the like are not embedded in the wood pieces and the plastic pieces, and the brass nails 3 and the like are knocked off by the cutting and crushing blade 61 and the wood pieces and the plastic pieces are in a state close to the original shape without damaging the head. To be separated. Moreover, the base plate 2 is supported on the upper surface of each support bar 34 in a state where the back surface 2b is aligned with the normal line m of the outer peripheral surface of the rotary blade 62, so that the back surface 2b of the base plate 2 is cut and crushed. The cutting is performed in a direction substantially orthogonal to 61, and the brass nails 3 and the like are reliably beaten by the cutting and crushing blade 61 from the pulling direction in which the brass nails 3 and the like are most likely to fall off, so that the wood piece and the plastic piece can be separated more reliably.

On the other hand, in the other crushing step C, the remaining crushed parts separated in the above crushing step A are sequentially sheared and crushed by the crushing device 11.
Then, it is repeatedly crushed by passing through the sieve 12 from the shear crushing device 11 to a predetermined size.

Thereafter, in the carrying step E, the crushed pieces crushed in the bed crushing step B are transported by the first discharge conveyor 13a, while the crushed pieces crushed in the other crushing step C are transferred by the second discharge conveyor 13b. The crushed pieces that have been transported and transported by both discharge conveyors 13a and 13b are collectively transported by the transportation conveyor 14 to the sorting step D.

Then, the transportation conveyor 1 in the above-mentioned transportation step E.
The sorting step D starts from the middle of the process.

In this sorting step D, the transport conveyor 1
From the crushed pieces on 4, the steel strip 4, split pins 5, studs, screws, and other steel parts (ferromagnetic material) are sorted out by a small magnetic sorter 15 and taken out.

Then, only the brass nail 3 is flipped out by the magnet pulley 16 from the remaining crushed pieces obtained by taking out only the steel component pieces from the transport conveyor 14 and taking them out. Thereby, the brass nails 3 can be easily selected, and the brass nails 3 in a state close to the original shape can be effectively reused.

Thereafter, the shredded pieces such as wood pieces and plastic pieces finally transported by the transport conveyor 14 are repeatedly shredded by the shredder 17 through the fine sieve 18 until they become shredded pieces. Then, the shredded pieces such as the wood pieces and the plastic pieces are dropped into the passage 19a of the wind power sorter 19 to apply the wind force of the propeller fan 20 from the side, and only the light wood powder and the plastic powder are applied by the wind force of the propeller fan 20. Is blown away to the distant passage 19b for selection, while wood and plastic pieces heavier than wood powder and plastic powder are used for propeller fan 2
Regardless of zero wind force, it is dropped as it is and sorted. With this, brass nails 3 sorted by the wind sorter 19
And wood powder and plastic powder that do not contain metal such as steel component pieces have a diameter of 12 to 20 mm and a length of 40 to 60.
It can be solidified to a size of about mm and reused as a fuel for small-scale power generation or as an auxiliary fuel such as a cement production kiln in a cement manufacturing device. On the other hand, wind power sorter 1
The plastic strips and wood strips selected in 9 can also be solidified and reused as a fuel in which metals such as brass nails 3 and steel component pieces do not coexist, according to the application.

The present invention is not limited to the above-mentioned embodiment, but includes various modifications. For example, in the above-described embodiment, the rotation direction of the rotary cutting tool 62 is the opposite direction opposite to the driving direction of the brass nail 3 on the base plate 2 on each support bar 34, but the driving of the brass nail on the base plate is performed. The rotary blade may be rotated around the same direction as the direction. In that case, the cutting and crushing blade is formed as a parallel blade that cuts at an acute angle with respect to the back surface of the base plate according to the rotation direction of the rotary blade.

Further, in the above embodiment, the rotary blade 6
Each support bar 34 in a state in which the back surface 2b of the base plate 2 is substantially aligned with the normal line m of the rotation locus X (circle) of the cutting and crushing blade 61 of FIG.
Although it is supported on the upper surface of the base plate, the back surface of the base plate does not necessarily have to be aligned with the normal line of the rotation locus of the cutting and crushing blade of the rotary knife. You may make it match on the normal line of.

In the above embodiment, the pachinko machine is used as the game machine, but it goes without saying that it can be applied to game machines such as smart ball machines.

As described above, according to the base plate crushing device of the gaming machine in the invention described in claim 1, the base plate is opposed to the cutting crushing blades which are opposed to each other over the entire width of the downstream end in the feeding direction of the base plate. Since it pushes it onto the guide support means by the feeding roller and cuts and crushes it, the cutting of the base plate is performed from the direction parallel to the nail driving direction, and while maintaining the nail in its original shape, it is possible to remove wood and plastic pieces. Separation can be easily performed, and thus nails and pieces of wood and plastic can be effectively reused.

According to the base plate crushing device of the gaming machine of the second aspect of the present invention, since the rotary blade is rotated in the opposite direction opposite to the nail driving direction, the nail or the like is in a state closer to the original shape. It can be separated from wood and plastic pieces.
